treated the remainder with oil, as usual. The results when I 

 saw the trees w'ere startling". Where the oil was used, fruit in 

 great quantity, almost or entirely free from scale. First qual- 

 ity in every respect; both apple and what remained of pear; 

 2,000 baskets of Bartletts, all in good shape, having been prev- 

 iously taken off. In the lime-sulphur-salt section, fruit all 

 spotted and gnarled, plenty as to crop, but much of it unsale- 

 able and little of first quality. Pear almost worse than apple. 

 The winter applicatioii had been as nearly w'asted as anything 

 can possibly be, and I doubt whether the trees could have been in 

 worse condition had there been no treatment whatever. 



In an apple orchard in Burlington county I made inspections 

 twice, during September. These trees, in full beari'ig and ex- 

 cellent general condition, had been sprayed with the boiled wash 

 during the winter of 1902-03, and the owner had been enthu- 

 siastic about the good result ; and with reason, as T found by 

 personal examination. He determined tO' make a final and com- 

 plete job of it in the winter of 1903-04, and had two steam 

 sprayers at work, plastering on the boiled wash as thoroughly 

 as such a jo^b can ever be done. The result in September was 

 a greater scale infestation than ever before, with twigs 

 and branches in some cases beginning tO' die on the more sus- 

 ceptible trees. So thorough had the application been, that 

 traces of it were present on trunk and older branches in mid- 

 September. 



The owner found, too, on figuring the cost, that this wash is 

 really about as expensive as any application that can be put on, 

 when the cost of making and the quantity needed is considered. 

 It is not a cheap wash by any means, and it is hard on the ap- 

 paratus as well as 011 the men. 



An explainable peculiarity was noted on some apple trees 

 that had not been very scaly, had been very thoroughly treated, 

 and on which the fruit became badly infested very early. In 

 these cases the applications had been made late and held on well ; 

 but toward the tips of the twigs the fine, dense pubescence of 

 plant hair, had caught and held the lime wash away from actual 

 contact with the wood, and with the scale that had set on it. 

 The first hatching very naturally made its way to the fruit, as 

 the most attractive place for setting, and the latter broods re- 

 mained as near at home as possible; giving a badly infested 

 crop oil a lightly infested tree. This feature is really a weak 

 point in the lime and sulphur combinations. They are all so 

 thick that the tendencv is to put them on in a coarse spray, which
